On his maternal side, his great-grandfather was Lt.-Gen. Sir Albert Conyngham. His ancestors, Scottish Protestants whose name was spelt Cunningham, had come the Ireland during the Plantation of Ulster. His grandfather was Major General Henry Conyngham, who claimed significant lands in County Meath, including Slane Castle. Burton's uncle Henry Conyngham served in the Irish and British Parliaments. He was created Baron Conyngham of Mount Charles in 1753 and Viscount Conyngham in 1756. On 4 January 1781, he was further elevated as Earl Conyngham and additionally created Baron Conyngham, this time with a special remainder to his eldest nephew.
